Electric shut-off valve, also called electric door, is the most widely used type of valve. It is different from electric ball valve. It is popular because of the low friction between the sealing surfaces during opening and closing. The opening height is not large, the manufacturing is easy, the maintenance is convenient, and it is not only suitable for medium and low pressure, but also suitable for high pressure. The closing principle of the electric shut-off valve is to rotate the valve bar by the electric thrust so that the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the medium from flowing. The electric stop valve only allows the medium to flow in one direction and is directional when installed. The structural length of the shut-off valve is larger than that of the gate valve, and the fluid resistance is large. When the machine is operated for a long time, the sealing reliability is not strong.
